3 Claims.

This invention relates to an elbow fitting for wallsupported waterclosets. These closets are usually supported on a wall by means of boltsthat passthrough the wall, and secure the closet to an elbow fitting onthe rear side of the wall. This elbow connects with the sewage wastepipe. The opening through the wall is usually made of considerablylarger diameter than the pipe connection, or thimble, that passesthrough the wall from the delivery orifice of the closet, and it is theusual practice to provide the elbow fitting with a plate that extendsdown from the upper portion of the elbow, and this plate constitutes aface plate to which the bolts for sup porting the closet bowl arefastened, the bolts extending from the face plate through the wall.These bolts, which secure the closet bowl to the wall usually include asingle lower bolt, which is located in substantially the same verticalplane as the axis of the down leg of the elbow fitting. A portion of theface plate that extends down to the floor of such fittings is usuallynot of great width, and in shipping these fittings there is' some dangerthat this portion of the face plate will become roken; The .generalobject of this invention is to provide fittings of this type withfeatures of construction, which will operate to provid-eian effectivebrace for the lower portion of the face plate.

When a lower bolt, such as referred to above, is employed located inline withthe down leg of the elbow, it is not possible to insert thisbolt from the back of the plate, and hence it has been usually necessaryto introduce such a bolt 1 from the forward side of the plate and applythe nut in the narrow space between the down leg of the elbow and thedownward extension or supporting leg of the face plate. By reason ofthe-very narrow space in which the nut is located, it is relativelyinaccessible and difficult to tighten up. One of the objects of thepresent invention is to provide a construction which will facilitate theapplication of the bolt with the bolt head located between the faceplate and the down leg of the elbow, and to construct the bracing meansbetween the elbow and the face plate in such a way that it will operateeffectively as a brace, and at the same time prevent rotation of thebolt head when the nut on the forward side of the plate is beingtightened up.

Further objects of the invention will appear hereinafter.

The invention consists in the novel parts and combination of parts to bedescribed hereinafter,

all of which contribute to produce an efficient fitting for wallsupported water closets.

A preferred embodiment of the invention is described in the followingspecification, while the broad scope of the invention is pointed out inthe appended claims.

In the drawing:

Fig. 1 is avertical section through the supporting plate for the closet,and showing the closet in side elevation, and also the elbow fitl tingembodying my invention. This view also indicates the floor level, andindicates in dotted lines the neck that connects to the sewerageWaste'pipe.

Figure 2 is a vertical section through the supl5 porting plate andthrough the elbow fitting, in a plane passing through the longitudinalaxis of the down leg of the fitting, and this View shows the rearportion of the closet broken away so as to illustrate the connection tothe delivery orifice of the closet. This view is upon an enlarged scale,and shows the forward portion of the closet broken away. It also shows aportion of the waste pipe connection in cross section and broken away.

Figure 3 is an elevation of the elbow fitting on the side of the faceplate.

Figure 4 is a horizontal section taken about on the line 4-4 of Fig. 2,and further illustrating details of the construction of the fitting.

Referring more particularly to the parts, I represents a closet of anycommon construction, which is supported-on a supporting wall 2. This isusually accomplished by providing a flange 3 at the rearof the closet,which is secured to the wall by bolts, as will be described moreparticularly hereinafter. In-the present instance, the delivery orifice4'. of the bowl is clamped up against a neck or thimble 5, which extendsthrough an opening 6 in'the wall from its rear 40 side, and this neck iseither integral with or screwed into an elbow fitting 1. This elbowfitting has a down leg 8, which extends down, in a substantiallyvertical position, and the lower end at the floor line 9 connects to awaste pipe or neck I ll extending up from the same. In the presentinstance, the closet is secured by three bolts, including two bolts suchas the bolt I! (see Fig. 1) and a lower bolt l2. The two bolts II arelocated on each side of the closet, and the lower bolt I2 is verticallyin line with the central axis of the bowl and the central axis of thedown leg 8 of the elbow 1. The elbow I also includes a face plate l3.The lower portion of the face plate I3 is preferably of reduced width(see Fig. 3) and extends down to the floor so that its lower end restson the floor, and to support the weight of the elbow fitting l and itsextension or thimble 5..

The space between the down leg 8 and the face plate I3 is quite narrow,as indicated in Fig. 2, and the head of the lower bolt at this point isrelatively inaccessible to a workman with a wrench. In some cases, thesupporting plate is not tiled on the outer side, but in someconstructions the head of the bolt at the back of the plate is plasteredin and made completely inaccessible by other workmen before the plumbercommences to install the closet, which must be done after the tilesetters have set the tiles on the face of the wall. The inaccessibilityor the bolt head at the back of the plate is probably the reason for theadoption of the custom of not using a bolt with a head but using insteada double-threaded stud bolt, which has been mounted by means of athreaded connection in the face plate with a clamping nut on the innerend toreceive a clamping nut that seats against the inner face of theplate. In some constructions, the back of the plate is completelyinaccessible. It is advantageous to provide a siot for the lower bolt,enabling this bolt to be set at the proper height to enable it to alignperfectly with the bolt hole in the flange of the closet.

In accordance with my invention, I provide the lower portion of the faceplate l3 with a bolt slot IS, the upper end of which is enlarged to forman opening 31, through which the head l5 of the bolt may be passed. Inassembling the parts, the head E5 of the bolt l2 would be insertedthrough the enlarged opening I! and the bolt would then be dropped downin the slot to a point opposite the corresponding hole in the flange ofthe closet. In order to prevent the bolt head l5 from rotating, and atthe same time to form the necessary brace for integrally connecting thedown leg 8 and the lower portion of the face plate, I provide twointegral webs I!) that connect these parts, and these webs are locatednear enough together so that they will lie near the fiat sides 20 of thebolt head I5 (see Fig. 4). In this way, these integral webs will operateto prevent breakages of the fittings in shipping them, and will alsofacilitate the attachment of the fitting to the closet. The upper boltsH, in accordance with the usual practice, may be constructed as studbolts passing through the face plate I3 with a jam nut ll clamped upagainst the back of the face plate.

The wall 22 of .the closet around the delivery orifice 4 is preferablyprovided with the usual annular groove 23 that registers with a similarannular groove 24 at the adjacent end of the neck or thimble 5. Thesehalf round grooves 23 and 24 form an annular socket to receive a gasket25. If this gasket 25 is made of metal, it will also assist insupporting the closet. The elbow fitting I may be provided with theusual air vent pipe 26.
